I THERE,
I WHANT TO CONTROL MY RECEVEIVER BOSE AV35 BY USING RS232.
I HAVE A GLOBAL CACHE ITACH IP2SL AND A CABLE 3.5MM JACK TO DB9 CONNECTOR.
BUT I HAVE NO CODE FOR THIS RECEVEIR I SAW SOME CODE ON A PDF ON THIS SITE BUT ITS NOT WORKING FOR ME.
PLEASE IF SOMEONE HAVE DO SOMETHING LIKE THAT GIVE ME SOME ADVICE TO CONTROLE IT.
TKS

i found this for the bose protocole:

5 The Communication Protocol
The Client only sends Command packets, which are of two types:
1) A Control packet which requests the Console to do something
2) A Query packet which requests information from the Console
The Console sends four types of packets:
1) A Ready packet which indicates the Client can send another packet.
2) A Response packet which contains information requested by a Query packet
3) A Notification packet which indicates an event that occurred on the Console
4) An Error packet which indicates a problem with a packet sent by the Client.
The Command packets and the Response packet associated with them are listed in section 6 Client Commands and Console Responses.
5.1 Notational Conventions
Base 16 (hexadecimal) is used to represent the contents of packets. Base 10 is used everywhere else unless the number is preceded by 0x which indicates hexadecimal.
Numbers occurring in the Payload field which are two or more bytes in length are sent using the so called little-endian byte ordering, which sends the least significant byte (LSB) first. Thus the number 350 decimal (0x015E) when sent, for example as the key hold time for the key press command (See Section 6.4 KP - Simulate a Key Press), would be sent as 0x5E01.
The Exclusive Or (XOR) operation is indicated by the ―^‖ character. This is a bitwise operation on two bytes, which results in a 1 if the two corresponding bits are different and a 0 if they are the same (see Table 4-3 The XOR Operator.)
5.2 Issuing Commands to the Console
To control or query the Console, the Client sends a Command packet and waits for packets from the Console. The Console does not send a Response packet for all commands but will always send a Ready packet. In rare circumstances an Error packet is sent instead of a response, but will always be followed by the Ready packet. The commands and their responses are described in section 6 Client Commands and Console Responses. (See also section 5.3.1 The Ready Packet and section 5.3.3.Error Packets)
Note: The Console sometimes sends Notification or Error packets which can come at any time including immediately after the Client issues a command packet. To understand how to parse Console packets, see section 5.3 Interpreting Packets from the Console.
Regardless of whether the Console sends a response packet or not, the Console always sends a Ready Packet after every Client command packet. The Ready Packet indicates the current command has been accepted and the Client can send another command subject to protocol timing (see section 5.4 Protocol Timings). The Client must wait for the Console's response and must not issue another command until it receives a Ready Packet. See Section 5.3.1 The Ready Packet.
In general, the resulting Console state change to a control command (e.g. source change, Room On/Off) has not been performed by the time the Ready command is sent. A query command can be used if needed to determine when the state change has occurred.


this for simulate a key press


Simulate a Key Press

Use this command to simulate pressing a key on the Console or a remote. This is the primary command for controlling the system.
Client sends: 0b 00 01 04

Checksum
The exclusive or (XOR) of all bytes in this packet (including length) which preceded the checksum byte
Note there is no command response from the Console for this command. The Ready packet will be sent by the Console after the command has been processed as usual. As always, the Ready Packet must be received by the Console before sending another command.
Note: If Key Press notification is enabled, the Key Press notification for that key will be sent by the Console and may arrive (as a notification packet) before the Ready packet. See section 5.3.4.1 Key Press Notification Packets.

and this for keys press codes

Key Press Codes
These keys can be sent using the KP command. They will also be the values listed in Key Press notification packets. These are also the codes received from an Infrared (IR) remote.
(See Sections 6.4 KP - Key Press and Section 5.3.4.1 Source Enumerators.)
